ABRAHAM W. LOZIER, ORANGE, NEW JERSEY, ASSIGNOR, BY MESNE ASSIGNMENTS, TO MRS. J. DE LA M. LOZIER, OF NEW YORK, N. Y.

IMPROVEM ENTI IN HEALTH-LIFTS.

Specification forming part of Letters Patent No. 190,150, dated May 1, 1877; application filed v September 29, 1876.

To all whom it may concern Be it known that I, ABRAHAM WITToN Lo- ZIER, M. D., of Orange, inthe county of Essex and State of New Jersey, haveV invented a new and Improved Health-Lift, of which the following is a specification:

Figure 1 is a vertical longitudinal central section of my improved health-lift. Fig. 2 is a top view thereof; Fig. 3, a vertical transverse section, on an enlarged scale, on the line c c, Fig. 2;' Fig. 4, a vertical transverse section on the line k k, Fig. l; Fig. 5, a detail side view, on an enlarged scale, of the liftinglever; Fig. 6, a detail crosssection through the end of the equalizer-bar. Fig. 7 is an enlarged side view of a handle, M. Fig. 8 is an end view of the adjustable weight.

Similar letters of reference indicate corresponding parts in all the figures.

This invention relates to a peculiar. construction and arrangement of lifting apparatus handle and chain-lock used in health-lifts and for analogous purposes; and consists, principally, in a peculiar arrangement of a lifting-lever'used between the lifting rope or chain and a counterbalancingweight. The invention also consists in other features of improvement, all as hereinafter more fully described.

In the accompanying drawing, A represents the base or bed plate of the machine, sup. porting rigidly-projecting standards or frame B, on which is hung by a pivot or axle, a., the lever C. (Shown more clearly in Fig. 5.) This lever is forked at its upper part, or slotted, as indicated in Fig. 4, and carries in its Yfork or slot a friction-rollenb, which is hun g on a pin, d, that has its bearings in the upper jaws of the lever O. The lower end of the lever O is preferably segmental in form, and connects with arope or chain, D, that connects either with a single lifting-handle, E, or with an equalizer cross-bar, L, said rope or chain passing around a friction-roller, e, before reaching said handle E; but this friction-roller may be dispensed with in case a horizontal pull'or side lift is desired. When the equalizer-bar L is used its ends connect by chains or cords pp with handles M. (Shown in Figs. l and 2.) F is the weighted bar, which is to be lifted by the operator. This bar has its nearest orv front end provided with downwardly-projecting lugsf, which are by pins g pivotedin the g standards B, as shown, said pivot-pins g being -the handle E or handles M M will vibrate theV lever O and thereby swing its upper -end backward, causing the friction-roller b to approach the pivot g, and in so doing to ride on the eccentric toe IL of the barF, and'swing said bar I on its pivot g. Now, it is clear that the farther the lever C is thus vibrated the nearer will the rollerb approach the pivot g of the weighted bar; or, in other words, the nearer the 't'ulcrum of the lever F will be to the power applied, and, consequently, the more difficult will it be to vibrate said lever againstV the counteracting influence of its weight IG. This is the principle to be attained by my invention, to wit: the gradually-increasing resistance of the Weight to the action of the operator.

Another feature of the invention consists in the use of a simple trigger attachment, '11, to the lever C, which, when the weighted bar F has been elevated to its greatest height reaches and acts upon a hammer, j, and causes the same to strike an alarm or gong, L.

A further feature of this invention has reference to the construction of the adjustable weightGr, which is made in the form of a crossbar riding on the bar F and adjustable thereon, and which can be fastened thereto by a suitable set-screw. The ends of this weight Gr are inade'hollow, as shown in Fig. 3, so that they may be more or less 1filled with additional weight, or emptied, as may be desired, the cavities m m being closed by suitable gates n. An additionalweight` may be placedv on the bar F whenever desired, and on any suitable part thereof. The end of the chain or rope connects with the handle M by passing through an aperture into a small chamber, o,

whichj is closed at one side by a pivoted latch,

q, and at the front by another latch, fr, the,

the length of the handle may be regulated to suit taller or shorter persons. A scale may be formed on one vof the parts lof-the handle y to allow accurate adjustment.

The single handle E is made with adjustable rings u u, working on a scale, so that they may gbe placed exactly as far apart asthe op..

eraton-requires Ethem, and always equidistant` from the middle :ofthe handle.

I- claim as my invention- The luglstmaybe dispensed withz l. Imalliftingapparatus, thercom-bina-tion of the y lever G, carryingfthe friction-roller gb, with the weighted bar F, having the toe h, substantially as specified.
